I'll tell what I believe to be true, but am prepared to be corrected.
I don't think much from a 2 or 4 door sedan is going to help on a 2 Dr hardtop, - except maybe the very middle.
The windshields on the sedans are sloped differently than the hardtop (and probably convertible).
The same with the rear glass, made for people in the backseat.
Now I have grafted 4 dr rears, - frame/body from the back of the rear wheel-arch, they fit near perfect on a 2 Dr, right down to the spotweld location.
I recently found the fronts to be interchangeable as well.
Good luck
